Extrema Ratio - Folder RAO Desert Warfare

The RAO is a survival knife, not a big folder but a compact field knife with a strong and heavy blade and a very safe locking system; an extra safe device that turns the folder into a real fix blade knife.  

The safety device is a steel pin that can be hand screwed through two holes placed by the guard zone of the massive anticorodal aluminum alloy handle. This device is necessary when the knife is used for larger chopping tasks. 
  
The sheath is also an essential part of the system containing a diamond sharpener. It also allows the user to carry the knife in an open condition, making frequent use easier. The sheath can be hung on equipment or standard belts thanks to MOLLE system.
